I am running windows 8 natively and have installed Ubuntu 14 from their download page. I believe I have installed the 32bit version instead of the 64bit version, because it will not load the option to boot into Ubuntu at startup. I have to restart holding shift to get into an option to reboot a sata drive that has this version of ubuntu on it. What is the best course of action here? Uninstall Ubuntu? Upgrade somehow?
Either you can use boot-repair from an ubuntu live usb or easyBCD from Windows.
